I vote for lightly salted peanuts and raisins. While at home, I prefer the unsalted peanuts. On the road, I think the bit of added salt keeps the body working longer. For chocolate, I carry a bar of Lindt Dark Chocolate in my handbar bag tucked between enough stuff so that it doesn't melt. There is nothing like freewheeling on a deserted road sucking on dark chocolate.
